valina [46]

Answer:

I will need to buy 22.5 pounds of turkey and pay $23.63

Step-by-step explanation:

Proportions

Each person is planned to eat 2 x 3/8 pound servings of turkey for thanksgiving dinner. This means each person will eat

$2\cdot\frac{3}{4}=\frac{3}{2}$

pounds of turkey.

There are going to be 15 people at the dinner, thus the total turkey needed is:

$15\cdot\frac{3}{2}=22.5~pounds$

The turkey costs $1.05 per pound, thus the total cost is

22.5*$1.05 = $23.63

I will need to buy 22.5 pounds of turkey and pay $23.63

What is the value of v? 4/5(v−7)=2

Nostrana [21]

4/5(v - 7) = 2...distribute the 4/5 thru the parenthesis
4/5v - 28/5 = 2 ...multiply everything by 5
4v - 28 = 10...add 28 to both sides
4v = 10 + 28
4v = 38
v = 38/4 reduces to 19/2 or 9 1/2 <==
